The Backup DAO is built with an all-stainless steel slide and frame in a matte finish, paired with black checkered synthetic grip panels for a secure hold. The compact package is designated micro size and is made in the USA.
It operates on a locked-breech, recoil-driven system with a double-action-only trigger. The design omits a manual safety and slide stop lever for simplicity, and the ejection port is on the right side of the slide.
Sight alignment is straightforward with a small pinned front blade and a fixed trench rear that is integral to the slide. This low-profile setup is consistent with the pistol’s ultra-compact intent.
Chambered in .45 ACP, the single-column detachable box magazine provides a stated 6+1 capacity. The heel-type magazine release supports a slim profile and secure magazine retention.
This example carries the Irwindale, California rollmark, identifying it with that production period of AMT manufacturing.
